The terms alien abduction or abduction phenomenon describe "subjectively real memories of being taken secretly against one's will by apparently nonhuman entities and subjected to complex physical and psychological procedures".[1] Such abductions have sometimes been classified as close encounters of the fourth kind. People claiming to have been abducted are usually called "abductees"[2] or "experiencers".

Typical claims involve being subjected to a forced medical examination that emphasizes their reproductive system.[clarification needed][5] Abductees sometimes claim to have been warned against environmental abuse and the dangers of nuclear weapons.[6] While many of these claimed encounters are described as terrifying, some have been viewed as pleasurable or transformative.

The first alleged alien abduction claim to be widely publicized was the Betty and Barney Hill abduction in 1961.[7] Reports of the abduction phenomenon have been made around the world, but are most common in English speaking countries, especially the United States.[4] The contents of the abduction narrative often seem to vary with the home culture of the alleged abductee.[4]

Mainstream scientists reject claims that the phenomenon literally occurs as reported. However, there is little doubt that many apparently stable persons who report alien abductions believe their experiences were real. As reported in the Harvard University Gazette in 1992, Dr. John E. Mack investigated over 800 claimed abductees and "spent countless therapeutic hours with these individuals only to find that what struck him was the 'ordinariness' of the population, including a restaurant owner, several secretaries, a prison guard, college students, a university administrator, and several homemakers … 'The majority of abductees do not appear to be deluded, confabulating, lying, self-dramatizing, or suffering from a clear mental illness,' he maintained."[9] "While psychopathology is indicated in some isolated alien abduction cases," Stuart Appelle et al. confirmed, "assessment by both clinical examination and standardized tests has shown that, as a group, abduction experients are not different from the general population in term of psychopathology prevalence."[10] Other experts who have argued that abductees' mental health is no better or worse than average include psychologists John Wilson and Rima Laibow, and psychotherapist David Gotlib.[11]

Some abduction reports are quite detailed. An entire subculture has developed around the subject, with support groups and a detailed mythos explaining the reasons for abductions: The various aliens (Greys, Reptilians, "Nordics" and so on) are said to have specific roles, origins, and motivations. Abduction claimants do not always attempt to explain the phenomenon, but some take independent research interest in it themselves and explain the lack of greater awareness of alien abduction as the result of either extraterrestrial or governmental interest in cover-up. Mack has cited more mundane reasons for the lack of general awareness concerning the data: "The most intense demand for alternative explanations tends to come from those who are either unfamiliar with the rich complexity of the abduction phenomenon, or from those who are so wedded to a worldview" that they find the phenomenon prima facie unacceptable.[12]

History

Though these two cases are sometimes viewed as the earliest abductions, skeptic Peter Rogerson[13] notes they were only the first "canonical"[clarification needed] abduction cases, establishing a template that later abductees and researchers would refine but rarely deviate from. Additionally, Rogerson notes purported abductions were cited contemporaneously at least as early as 1954, and that "the growth of the abduction stories is a far more tangled affair than the 'entirely unpredisposed' official history would have us believe." (The phrase "entirely unpredisposed" appeared in folklorist Thomas E. Bullard's study of alien abduction; he argued that alien abductions as reported in the 1970s and 1980s had little precedent in folklore or fiction.)

Paleo-abductions

While "alien abduction" did not achieve widespread attention until the 1960s, there were many similar stories circulating decades earlier. These early abduction-like accounts have been dubbed "paleo-abductions" by UFO researcher Jerome Clark.[14]

In the November 27, 1896 edition of the Stockton, CaliforniaDaily Mail, Colonel H. G. Shaw claimed he and a friend were harassed by three tall, slender humanoids whose bodies were covered with a fine, downy hair who tried to kidnap the pair.[14]

Rogerson writes that the 1955 publication of Harold T. Wilkins's Flying Saucers Uncensored declared that Karl Hunrath and Wilbur Wilkinson, who had claimed they were contacted by aliens, had disappeared under mysterious circumstances; Wilkins reported speculation that the duo were the victims of "alleged abduction by flying saucers".[13]

Contactees

The UFO contactees of the 1950s claimed to have contacted aliens, and the substance of contactee narratives – in which the beings express the intent to help mankind stop nuclear testing and prevent the otherwise inevitable destruction of the human race.

Two landmark cases

An early alien abduction claim occurred in the mid-1950s with the Antonio Vilas Boas case, which did not receive much attention until several years later.

Widespread publicity was generated by the Betty and Barney Hill abduction case of 1961, culminating in a made-for-television film broadcast in 1975 (starring James Earl Jones and Estelle Parsons) dramatizing the events. The Hill incident was probably the prototypical abduction case and was perhaps the first in which the claimant described beings that later became widely known as the Greys and in which the beings were said to explicitly identify an extraterrestrial origin.

Later developments

Dr. R. Leo Sprinkle (University of Wyoming psychologist) became interested in the abduction phenomenon in the 1960s. For some years, he was probably the only academic figure devoting any time to studying or researching abduction accounts. Sprinkle became convinced of the phenomenon's actuality, and was perhaps the first to suggest a link between abductions and cattle mutilation. Eventually Sprinkle came to believe that he had been abducted by aliens in his youth; he was forced from his job in 1989.[15]

Budd Hopkins had been interested in UFOs for some years. In the 1970s he became interested in abduction reports, and began using hypnosis to extract more details of dimly remembered events. Hopkins soon became a figurehead of the growing abductee subculture.[16]

The 1980s brought a major degree of mainstream attention to the subject. Works by Budd Hopkins, novelist Whitley Strieber, historian David M. Jacobs and psychiatrist John E. Mack presented alien abduction as a genuine phenomenon.[16] Also of note in the 1980s was the publication of folklorist Dr. Thomas E. Bullard's comparative analysis of nearly 300 alleged abductees.

With Hopkins, Jacobs and Mack, accounts of alien abduction became a prominent aspect of ufology. There had been earlier abduction reports (the Hills being the best known), but they were believed to be few and far between, and saw rather little attention from ufology (and even less attention from mainstream professionals or academics). Jacobs and Hopkins argued that alien abduction was far more common than earlier suspected; they estimate that tens of thousands (or more) North Americans had been taken by unexplained beings.[16]

Furthermore, Jacobs and Hopkins argued that there was an elaborate process underway in which aliens were attempting to create human–alien hybrids, the most advanced stage of which in the "human hybridization program" are known as hubrids[17] (a portmanteau of human and hybrids), though the motives for this effort were unknown. There had been anecdotal reports of phantom pregnancy related to UFO encounters at least as early as the 1960s, but Budd Hopkins and especially David M. Jacobs were instrumental in popularizing the idea of widespread, systematic interbreeding efforts on the part of the alien intruders.

The descriptions of alien encounters as researched and presented by Hopkins, Jacobs and Mack were similar, with slight differences in each researcher's emphasis; the process of selective citation of abductee interviews that supported these variations was sometimes criticized – though abductees who presented their own accounts directly, such as Whitley Strieber, fared no better.

The involvement of Jacobs and Mack marked something of a sea change in the abduction studies. Their efforts were controversial (both men saw some degree of damage to their professional reputations), but to other observers, Jacobs and Mack brought a degree of respectability to the subject.

John E. Mack

Matheson writes that "if Jacobs's credentials were impressive," then those of Harvard psychiatrist John E. Mack might seem "impeccable" in comparison.[18] Mack was a well known, highly esteemed psychiatrist, author of over 150 scientific articles and winner of the Pulitzer Prize for his biography of T. E. Lawrence. Mack became interested in the phenomenon in the late 1980s, interviewing over 800 people, and eventually writing two books on the subject.

John E. Mack devoted a substantial amount of time to investigating such cases and eventually concluded that the only phenomenon in psychiatry that adequately explained the patients' symptoms in several of the most compelling cases was posttraumatic stress disorder.[19] As he noted at the time, this would imply that the patient genuinely believed that the remembered frightening incident had really occurred – the position Mack came to endorse.[20]

In June 1992, Mack and the physicist David E. Pritchard organized a five-day conference at MIT to discuss and debate the abduction phenomenon.[21] The conference attracted a wide range of professionals, representing a variety of perspectives. As their thanks for their efforts to focus a modest level of serious scientific attention on the perplexing "abduction" phenomenon by organizing this conference, Mack and Jacobs were awarded an Ig Nobel Prize in 1993.

Writer C. D. B. Bryan attended the conference, initially intending to gather information for a short humorous article for The New Yorker. While attending the conference, however, Bryan's view of the subject changed, and he wrote a serious, open-minded book on the phenomenon, additionally interviewing many abductees, skeptics, and proponents.

Abductees

The precise number of alleged abductees is uncertain. One of the earliest studies of abductions found 1,700 claimants, while contested surveys argued that 5–6 percent of the general population might have been abducted.[3]

Demographics

In a study investigating the motivations of the alleged abductors, Jenny Randles found that in each of the 4 cases out of 50 total where the experiencer was over 40 years of age, they were rejected by the aliens for "what they (the experiencers) usually inferred to be a medical reason."[22] Randles concludes "[T]he abduction is essentially a young person's experience."[22] Given the reproductive focus of the alleged abductions it is not surprising that one man reported being rejected because he had undergone a vasectomy.[23] It could also be partially because people over the age of 40 are less likely to have "hormonic" or reproductive activity going on.

Although abduction and other UFO-related reports are usually made by adults, sometimes young children report similar experiences.[24] These child-reports often feature very specific details in common with reports of abduction made by adults, including the circumstances, narrative, entities and aftermaths of the alleged occurrences.[24] Often these young abductees have family members who have reported having abduction experiences.[24] Family involvement in the military, or a residence near a military base is also common among child abduction claimants.[24]

Mental health

As a category, some studies show that abductees have psychological characteristics that render their testimony suspect, while others show that "as a group, abduction experients are not different from the general population in term of psychopathology prevalence".[4][10] Dr. Elizabeth Slater conducted a blind study of nine abduction claimants and found them to be prone to "mildly paranoid thinking," nightmares and having a weak sexual identity,[4] while Dr. Richard McNally of Harvard Medical School concluded in a similar study of 10 abductees that "none of them was suffering from any sort of psychiatric illness."[25]

Paranormal

Alleged abductees are seen by many pro-abduction researchers to have a higher incidence of non-abduction related paranormal events and abilities.[26] Following an abduction experience, these paranormal abilities and occurrences sometimes seem to become more pronounced.[26] According to investigator Benton Jamison, abduction experiencers who report UFO sightings that should have been, but are not, reported by independent corroborating witnesses often seem to "be 'psychic personalities' in the sense of Jan Ehrenwald."[26] Psychic Medium Danielle Egnew recounted multiple abduction experiences in her 2012 book True Tales of the Truly Weird, greatly detailing communication, technology and abduction methods of more than one alien race.[27]

Misc

According to Yvonne Smith, some alleged abductees test positive for lupus, despite not showing any symptoms.[28]

The abduction narrative

Although different cases vary in detail (sometimes significantly), some UFO researchers, such as folklorist Thomas E. Bullard[29] argue that there is a broad, fairly consistent sequence and description of events that make up the typical "close encounter of the fourth kind" (a popular but unofficial designation building on Dr. J. Allen Hynek's classifying terminology). Though the features outlined below are often reported, there is some disagreement as to exactly how often they actually occur.

Bullard argues most abduction accounts feature the following events. They generally follow the sequence noted below, though not all abductions feature all the events:

Capture. The abductee is somehow rendered incapable of resisting, and taken from terrestrial surroundings to an apparent alien spacecraft.

Conference. The abductors communicate with the abductee or direct them to interact with specific individuals for some purpose, typically telepathically but sometimes using the abductee's native language.

Tour. The abductees are given a tour of their captors' vessel, though this is disputed by some researchers who consider this definition a confabulation of intent when just apparently being taken around to multiple places inside the ship.

Loss of Time. Abductees often rapidly forget the majority of their experience, either as a result of fear, medical intervention, or both.

Return. The abductees are returned to earth, occasionally in a different location from where they were allegedly taken or with new injuries or disheveled clothing.

Theophany. Coinciding with their immediate return, abductees may have a profound sense of love, a "high" similar to those induced by certain drugs, or a "mystical experience", accompanied by a feeling of oneness with God, the universe, or their abductors. Whether this is the result of a metaphysical change, Stockholm syndrome, or prior medical tampering is often not scrutinized by the abductees at the time.

Aftermath. The abductee must cope with the psychological, physical, and social effects of the experience.

When describing the "abduction scenario", David M. Jacobs says:

The entire abduction event is precisely orchestrated. All the procedures are predetermined. There is no standing around and deciding what to do next. The beings are task-oriented and there is no indication whatsoever that we have been able to find of any aspect of their lives outside of performing the abduction procedures.[30]

Capture

Abduction claimants report unusual feelings preceding the onset of an abduction experience.[31] These feelings manifest as a compulsive desire to be at a certain place at a certain time or as expectations that something "familiar yet unknown," will soon occur.[31] Abductees also report feeling severe, undirected anxiety at this point even though nothing unusual has actually occurred yet.[31] This period of foreboding can last for up to several days before the abduction actually takes place or be completely absent.[31]

Eventually, the experiencer will undergo an apparent "shift" into an altered state of consciousness.[31] British abduction researchers have called this change in consciousness "the Oz Factor." External sounds cease to have any significance to the experiencer and fall out of perception.[31] They report feeling introspective and unusually calm.[31] This stage marks a transition from normal activity to a state of "limited self-willed mobility."[31] As consciousness shifts one or more lights are alleged to appear, occasionally accompanied by a strange mist.[31] The source and nature of the lights differ by report; sometimes the light emanates from a source outside the house (presumably the abductors' UFO), sometimes the lights are in the bedroom with the experiencer and transform into alien figures.[31]

As the alleged abduction proceeds, claimants say they will walk or be levitated into an alien craft, in the latter case often through solid objects such as walls, ceilings or a closed window.[31] Alternatively, they may experience rising through a tunnel or along a beam of light, with or without the abductors accompanying them, into the awaiting craft.[31]

Examination

The examination phase of the so-called "abduction narrative" is characterized by the performance of medical procedures and examinations by apparently alien beings against or irrespective of the will of the experiencer. Such procedures often focus on sex and reproductivebiology. However, the literature holds reports of a wide variety of procedures allegedly performed by the beings. The entity that appears to be in charge of the operation is often taller than the others involved, and is sometimes described as appearing to be of a different species.[5][32]

Miller notes different areas of emphasis between human medicine and what is reported as being practiced by the abductors.[5] This could result from a difference in the purpose of the examination—routine diagnosis and/or treatment versus scientific examination of an unfamiliar species, or it could be due to a different level of technology that renders certain kinds of manual procedures unnecessary. The abductors' areas of interest appear to be the cranium (see below), nervous system, skin, reproductive system, and to a lesser degree, the joints.[5] Systems given less attention than a human doctor would, or omitted entirely include cardiovascular system, the respiratory system below the pharynx and the lymphatic system.[5] The abductors also appear to ignore the upper region of the abdomen in favor of the lower one.[5] The abductors do not appear to wear gloves during the "examination."[5] Other constants of terrestrial medicine like pills and tablets are missing from abduction narratives although sometimes abductees are asked to drink liquids.[5] Injections also seem to be rare and IVs are almost completely absent.[5] Dr. Miller says he's never heard an abductee claim to have a tongue depressor used on them.[5]

Subsequent abduction procedures

After the so-called medical exam, the alleged abductees often report other procedures being performed with the entities.[30] Common among these post-examination procedures are what abduction researchers refer to as imaging, envisioning, staging, and testing.[30]

"Imaging" procedures consist of an abductee being made to view screens displaying images and scenes that appear to be specially chosen with the intent to provoke certain emotional responses in the abductee.[30] "Envisioning" is a similar procedure, with the primary difference being that the images being viewed, rather than being on a screen, actually seem to be projected into the experiencer's mind.[30] "Staging" procedures have the abductee playing a more active role, according to reports containing this element.[30] It shares vivid hallucination-like mental visualization with the envisioning procedures, but during staging the abductee interacts with the illusionary scenario like a role player or an actor.[30]

"Testing" marks something of a departure from the above procedures in that it lacks the emotional analysis feature.[30] During testing the experiencer is placed in front of a complicated electronic device and is instructed to operate it.[30] The experiencer is often confused, saying that they do not know how to operate it.[30] However, when they actually set about performing the task, the abductee will find that they do, in fact, know how to operate the machine.[30]

Child presentation

Abductees of all ages and genders sometimes report being subjected to a "child presentation."[30] As its name implies, the child presentation involves the abduction claimant being shown a "child."[30] Often the children appear to be neither human, nor the same species as the abductors.[30] Instead, the child will almost always share characteristics of bothspecies.[30] These children are labeled by experiencers as hybrids between humans and their abductors, usually Greys.

Unlike Budd Hopkins and David Jacobs, folklorist Thomas E. Bullard could not identify a child presentation phase in the abduction narrative, even after undertaking a study of 300 abduction reports.[23] Bullard says that the child presentation "seems to be an innovation in the story"[23] and that "no clear antecedents" to descriptions of the child presentation phase exists before its popularization by Hopkins and Jacobs.[23]

Sexual contact

Often abductees will experience some kind of sexual contact with either aliens or other humanoids. There is also often an anal probe taken to obtain genetic material.

Less common elements

Bullard also studied the 300 reports of alien abduction in an attempt to observe the less prominent aspects of the claims.[6] He notes the emergence of four general categories of events that recur regularly, although not as frequently as stereotypical happenings like the medical examination. These four types of events are:[6]

The conference

The tour

The journey

Theophany

Chronologically within abduction reports these rarer episodes tend to happen in the order listed, between the medical examination and the return.[6]

After allegedly displaying cold callous disregard towards the abduction experiencers, sometimes the entities will change drastically in behavior once the initial medical exam is completed.[6] They become more relaxed and hospitable towards their captive and lead him or her away from the site of the examination.[6] The entities then hold a conference with the experiencer, wherein they discuss things relevant to the abduction phenomenon.[6] Bullard notes five general categories of discussion that occur during the conference "phase" of reported abduction narratives: An interrogation session, explanatory segment, task assignment, warnings, and prophecies.[6]

Tours of the abductors' craft are a rare but recurring feature of the abduction narrative.[6] The tour seems to be given by the alleged abductors as a courtesy in response to the harshness and physical rigors of the forced medical examination.[6] Sometimes the abductee report traveling on a "journey" to orbit around Earth or to what appear to be other planets.[6] Some abductees find that the experience is terrifying, particularly if the aliens are of a more fearsome species, or if the abductee was subjected to extensive probing and medical testing.

Return

Eventually the abductors will return the abductees to terra firma, usually to exactly the same location and circumstances they were in before being taken.[33] Usually, explicit memories of the abduction experience will not be present, and the abductee will only realize they have experienced "missing time" upon checking a timepiece.[33]

Sometimes the alleged abductors appear to make mistakes when returning their captives.[33] Famed UFO researcher Budd Hopkins has joked about "the cosmic application of Murphy's Law" in response to this observation.[33] Hopkins has estimated that these "errors" accompany 4–5 percent of abduction reports.[33] One type of common apparent mistake made by the abductors is failing to return the experiencer to the same spot that they were taken from initially.[33] This can be as simple as a different room in the same house, or abductees can even find themselves outside and all the doors of the house are locked from the inside.[33] Another common (and amusing) error is putting the abductee's clothes (e.g. pajamas) on backwards.

Realization event

Physician and abduction researcher John G. Miller sees significance in the reason a person would come to see themselves as being a victim of the abduction phenomenon.[34] He terms the insight or development leading to this shift in identity from non-abductee to abductee the "realization event."[34] The realization event is often a single, memorable experience, but Miller reports that not all abductees experience it as a distinct episode.[34] Either way, the realization event can be thought of as the "clinical horizon" of the abduction experience.[34]

Trauma and recovery

Most people alleging alien abductions report invasive examinations of their bodies[35] and some ascribe psychological trauma to their experiences.[36] "Post abduction syndrome" is a term used by abductees to describe the effects of abduction, though it is not recognized by any professional treatment organizations.[36] People who have a false memory which makes them believe that they have been abducted by aliens develop symptoms similar to posttraumatic stress disorder. People who believe they have been abducted by aliens usually have previous New Age beliefs, a vivid fantasy life, and suffer from sleep paralysis, according to a 2003 study by Harvard University.[37]

Support groups

Support groups for people who believed they were abducted began appearing in the mid-1980s. These groups appear throughout the United States, Canada and Australia.[38]

The role of hypnosis

Many alien abductees recall much of their abduction(s) through hypnosis.[39] Because of this, it is claimed by some skeptics that the vast majority of evidence for alien abduction is based on memories 'recovered' through hypnosis. Due to the extensive use of hypnosis, the abduction narratives are frequently explained by skeptics as false memories and suggestions by the hypnotherapist.[40]

Argument against the use of hypnosis

Alleged abductees seek out hypnotherapists to try to resolve issues such as missing time or unexplained physical symptoms such as muscle pain or headaches. This usually involves two phases, an information gathering stage, in which the hypnotherapist asks about unexplained illnesses or unusual phenomena during the patients lives (caused by or distortions of the alleged abduction), followed by hypnosis and guided imagery to facilitate recall. The information gathering enhances the likelihood that the events discussed will be incorporated into later abduction "memories".[41] Seven steps are hypothesized to lead to the development of false memories:[40]

A person is predisposed to accept the idea that certain puzzling or inexplicable experiences might be telltale signs of UFO abduction.

The person seeks out a therapist, whom he or she views as an authority and who is, at the very least, receptive to this explanation and has some prior familiarity with UFO abduction reports.

Alternatively, the therapist frames the puzzling experiences in terms of an abduction narrative.

Alternative explanations of the experiences are not explored.

There is increasing commitment to the abduction explanation and increasing anxiety reduction associated with ambiguity reduction.

The therapist legitimates or ratifies the abductee's experience, which constitutes additional positive reinforcement.

The client adopts the role of the "victim" or abductee, which becomes integrated into the psychotherapy and the client's view of self.

Argument for the use of hypnosis

Harvard psychiatrist John E. Mack counters this argument, noting "It might be useful to restate that a large proportion of the material relating to abductions is recalled without the use of an altered state of consciousness, and that many abduction reporters appear to relive powerful experiences after only the most minimal relaxation exercise, hardly justifying the word hypnosis at all. The relaxation exercise is useful to relieve the experiencer's need to attend to the social demands and other stimuli of face-to-face conversation, and to relieve the energies involved in repressing memories and emotion."[42]

Perspectives

There have been a variety of explanations offered for abduction phenomena, ranging from sharply skeptical appraisals, to uncritical acceptance of all abductee claims, to the demonological, to everything in between.

Some have elected not to try explaining things, instead noting similarities to other phenomena, or simply documenting the development of the alien abduction phenomenon.

Others are intrigued by the entire phenomenon, but hesitate in making any definitive conclusions. The late Harvard psychiatrist John E. Mack concluded, "The furthest you can go at this point is to say there's an authentic mystery here. And that is, I think, as far as anyone ought to go." (emphasis as in original)[43] Mack was unconvinced by piecemeal counterclaims, however, and countered that skeptical explanations naturally need to "take into account the entire range of phenomena associated with abduction experiences," up to and including "missing time," directly contemporaneous UFO sightings, and the occurrence in small children.[12]

Putting aside the question of whether abduction reports are literally and objectively "real", literature professor Terry Matheson argues that their popularity and their intriguing appeal are easily understood. Tales of abduction "are intrinsically absorbing; it is hard to imagine a more vivid description of human powerlessness." After experiencing the frisson of delightful terror one may feel from reading ghost stories or watching horror movies, Matheson notes that people "can return to the safe world of their homes, secure in the knowledge that the phenomenon in question cannot follow. But as the abduction myth has stated almost from the outset, there is no avoiding alien abductors."[44]

Matheson writes that when compared to the earlier contactee reports, abduction accounts are distinguished by their "relative sophistication and subtlety, which enabled them to enjoy an immediately more favorable reception from the public."

Skeptical perspectives

Skeptical perspectives assert that reports of people being kidnapped and subjected to forced medical examinations by extraterrestrial creatures do not occur literally as reported. Although being only one of many competing explanations for the phenomenon, it is the only one that is widely accepted by mainstream scientists and historians.

Various hypotheses have been proposed by skeptics to explain reports without the need to invoke controversial concepts such as intelligent extraterrestrial life forms. These hypotheses usually center on known psychological processes that can produce subjective experiences similar to those reported in abduction claims. Skeptics are also likely to critically examine abduction claims for evidence of hoaxing or influence from popular culture sources such as science fiction. One example of a comprehensive, skeptical analysis that focuses on the effects of mass marketing is art historian John F. Moffitt's 2003 book Picturing Extraterrestrials: Alien Images in Modern Mass Culture[45]

It is possible that some alleged abductees may experience spontaneous lucid dreams. This was reportedly proven by the OOBE Research Center during their mass alien abduction experiment (Los Angeles, USA, October 2011).[47]

It is possible that some self-described abductees may be mentally unstable or under the influence of recreational drugs.

In The Demon-Haunted WorldastronomerCarl Sagan points out that the alien abduction experience is remarkably similar to tales of demon abduction common throughout history. "There is no spaceship in these stories. But most of the central elements of the alien abduction account are present, including sexually obsessive non-humans who live in the sky, walk through walls, communicate telepathically, and perform breeding experiments on the human species. Unless we believe that demons really exist, how can we understand so strange a belief system, embraced by the whole Western world (including those considered the wisest among us), reinforced by personal experience in every generation, and taught by Church and State? Is there any real alternative besides a shared delusion based on common brain wiring and chemistry?"

Paranormal and conspiratorial

Some have argued that alien abduction is a literal phenomenon: extraterrestrials kidnap humans to conduct studies or experiments. This is a well-known popular explanation, but has seen very little support from most mainstream scientists.[citation needed]

Various authors, including Jacques Vallée and John E. Mack, have suggested that the dichotomy 'real' versus 'imaginary' may be too simplistic; that a proper understanding of this complex phenomenon may require a reevaluation of our concept of the nature of reality.

Testimonials

Abduction researcher Brian Thompson claims that a nurse acquaintance of his reported that during 1957 in Cincinnati she encountered a 3-foot-tall (0.91 m) praying mantis-like entity two days after a V-shaped UFO sighting.[32] This mantis-like creature is reminiscent of the insectoid-type entity reported in some abduction accounts.[32] He related this report to fellow researcher Leonard Stringfield.[32] Stringfield told him of two cases he had in his files where separate witnesses reported identical circumstances in the same place and year.[32]

While some corroborated accounts seem to support the literal reality of the abduction experience, others seem to support a psychological explanation for the phenomenon's origins. Jenny Randles and Keith Basterfield both noted at the 1992 MIT alien abduction conference that of the five cases they knew of where an abduction researcher was present at the onset of an abduction experience, the experiencer "didn't physically go anywhere."[49]

Brazilian researcher Gilda Moura reported on a similar case, the Sueli case, from her home country. When psychologist and UFO researcher Don Donderi said that these cases were "evidence of psychological processes" that did not "have anything to do with a physical alien abduction," Moura replied "If the Sueli case is not an abduction, I don't know what is an abduction any more."[49] Gilda Moura noted that in the Brazilian Sueli case during the abduction UFOs were observed.[49] Later, she claims the experiencer had eye burns, saw lights and there seemed to be residual poltergeist activity.[49]

Attempts at confirmation

It has been argued that if actual "flesh and blood" aliens are abducting humans, there should be some hard evidence that this is occurring.[4] Proponents of the physical reality of the abduction experience have suggested ways that could conceivably confirm abduction reports.

One procedure reported occurring during the alleged exam phase of the experience is the insertion of a long needle-like contraption into a woman's navel.[5] Some have speculated that this could be a form of laparoscopy.[5] If this is true, after the abduction there should be free gas in the female's abdomen, which could be seen on an x-ray.[5] The presence of free gas would be extremely abnormal, and would help substantiate the claim of some sort of procedure being done to her.[5]
